There's a simple word game that was recently conceived. This has not been fully developed. On the plus side, it's very easy to get components to play.
 

Materials:
Scrabble or bananagram pieces with letters. You can make your own letters with squares of paper, and you may store it in an envelope, but that's more work. Consider visibility, because these letters are publicly visible to other players. The other component is strips of paper which have secret 6-7-letter words.
 

Here's a quick and dirty description: You get letters from the draw pile or trading, your letters are publicly visible. You have a secret word, you win if you spell it. Your word letters can be from your letters, or someone else, as long as someone else's letter is part of their secret word.
 
 
 

BETTER LETTER

There are secret words, 6-7 letters long, on strips of paper. You can do this by making the words by yourself (giving you a bit of an advantage), having everyone toss in some words, or something else ("optional").

There are at least three players. More players are better because you get overlap with needed letters. You've got a draw pile of letters that are upside down. Players start with zero letters. Each player is randomly given a secret word, e.g., TURKEY, CARROT, SAFETY, WARTHOG.

A player's "hand" (tableau is a better word) is that player's letters. A player can have a maximum of seven letters per hand. These letters are on the table, publicly visible to all players.

During your turn you can A) Draw a letter from the draw pile or B) trade.
You can draw a letter from the draw pile and either exchange it for one of your letters or put it back in the draw pile. If you have fewer than seven letters you do not put letters back in the draw pile.
You can trade one of your letters with one letter from another willing player. If you fail to make the trade, you can still take a letter from the draw pile instead.

A player wins if he has the letters to spell his secret word during his turn. The letters for the word could include other players' letters, as long as the letter is part of other players' secret words. For example, you have TURQEYM (turkey), and you also point to the K in Ralph's letters. However, the K is not part of Ralph's secret word ("WARTHOG") which he does not have to reveal.

If a player announces that he can spell his word but fails, as in the above example, the player puts his letters back in the draw pile, and starts again with a new secret word.

Any player can restart during any of his or her turns, as long as the player has a hand of seven letters. The player replaces the secret word with a new secret word, and restarts with zero letters.
 
 
 
 

Lessons from testing:
For the first group (four) I forgot that you could trade. For the second group (three) nobody traded. Trading is .. well, think about it. Brain bendy. There might not be a point to trading.
I rather like the game, but more testing is required. I think of it as something ratty that can be thrown together and played with a variety of people for a short game.
Since players create the key words, they may know what another player is trying to spell, leading to a win. I'm not sure what to make of that.
During the first test the discard pile was face up, to distinguish it from the draw pile. This affected the game, as you can more easily see which letters a player does not want.
The rules are simple. Or at least I think they are simple. However, people in two groups had a hard time grasping the rules. This may be because the people with whom it was played are twits, had a hard time absorbing the rules for one reason or another (including covid). Or maybe the game is tricky and requires a slicker explanation.
Paper squares, three centimetres, were used. People got confused by letters like N and Z, so twits haphazardly marked the squares.
